  • Driving apparatus for industrial robot
    Patent number: 4739669
    Abstract: A driving apparatus for effecting linear movement of an industrial robot comprises a slide member axially slidably disposed within a frame, a ball nut secured to the slide member and a ball screw threaded through the ball nut and rotationally driven relative to the ball nut to effect linear movement of the ball nut along the ball screw accompanied by linear movement of the slide shaft. A bracket is adjustably mounted on the frame for rotatably supporting the shaft of the ball screw. The bracket can be displaced relative to the frame in the transverse direction of the slide member to align the axis of the ball screw with the axis of the slide member during assembly of the apparatus. A thrust bearing is disposed between the shaft of the ball screw and the bracket to absorb radial displacement and strain of the ball screw shaft.

  • Supporting mechanism of a linearly movable bearing
    Patent number: 4717265
    Abstract: A support mechanism for a cylindrical coordinate type industrial robot comprising a stationary upstanding tubular outer member and a displaceable inner member supported within the outer member to undergo axial displacement in upward and downward directions and angular displacement in clockwise and counterclockwise directions. The supporting mechanism includes a bearing interposed between the inner and outer members, the bearing including a retaining member rollably retaining thereon a plurality of rollable elements. An elastic balancing and restoring device for applying elastic biasing forces in opposite axial directions to the upper and lower ends of the retainer member is operative in the event the retainer member fails to maintain proportionate displacement with the inner member to temporarily increase the magnitude of the force difference between the oppositely directed elastic biasing forces in a direction effective to restore the proportionate displacement.
